(1) = 1 answer/part
Module 10
[the] nervous system
What are the two systems/subcategories apart of the nervous system?
Module 10
- Peripheral
- Central

(1) = 1 answer/part
Module 10
central nervous system (CNS)
What system is responsible for gathering information and for transmitting CNS decisions to other body parts?
Module 10
peripheral nervous system (PNS)
The peripheral nervous system (PNS) is made up of what kind of neurons? (2)
(2) = 2 answers/parts
Module 10
- sensory [neurons]
- motor [neurons]
The peripheral nervous system (PNS) does what to the central nervous system (1)?
(1) = 1 answer/part
Module 10
connects it (CNS) to the rest of the body
helps transmit CNS decisions to other body parts
Electrical cables (neural cables) formed from bundles of axons connecting the central nervous system with muscles, glands and sense organs defines what? (1)
(1) = 1 answer/part
Module 10
nerves
What kind of neuron carries messages from the body’s tissues and sensory receptors inward to the brain and spinal cord for processing?
Module 10
sensory [neurons]
What kind of neuron carry instructions from the central nervous system outward to the body’s muscles and glands?
Module 10
motor [neurons]
Between the sensory input and motor output, what kind of neuron helps process information in the spinal cord/brain?
Module 10
interneurons
Our peripheral system is made up of what two components?
Module 10
- somatic
- autonomic
What nervous system enables voluntary control of our sketal muscles? (conscious activity)
